SPECIFICATION forming part of Letters Patent No. 654,374, dated July 24,1900. Application filed IanuaryZO, 1900. Serial No. 2,148. (No model.)

To ctZZ whom it may concern:

Be it known that I, EDWIN H. WILSON, a citizen of the United States,'anda resident of Globe Village, in the county of Worcester and State ofMassachusetts, have invented a new and Improved Sand-Shield, of whichthe following is a full, clear, and exact description.

The purpose of this invention is to provide a superior means forexcluding sand from the j ournal-boxes of vehicle-hubs,which end Iattain by providing two peculiarly-constructed shield sections, one ofwhich is attached to the hub and the other of whi'ch is attached to theaxle, the parts coacting, so as to prevent the possibility of sand andlike matter entering the journal-box of the hub.

This specification is the disclosure of one form of my invention, whilethe claims define the actual scope thereof.

Reference is tobe had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in both views.

Figure 1 is a perspective View of the invention, showing the hubremoved; and'Fig. 2 is a sectional view illustrating the parts in place.The hub 3 of the wheel,with itsjournal-box 4, is mounted, as usual, onthe journal 5 of the axle 6, and to this hub 3, between the j ournalbox4 and the hub-band 7, a collar or annulus 8- is attached. This collar orannulus has a sharpened inner edge adapted to be driven slightly intothe hub, as indicated at the top of Fig. 2, and the collar 8 also hasspurs 9,

which serve to enter the hub to secure the collar in engagementtherewith, as shown.

.The inner edge of the collar is thickened and flared outward to form aflange 8, as shown. It will thus be seen that the collar is attached tothe hub to turn therewith around the axle and also that, owing to thesharpened outer edges of the collar 8, a sand-tight connection iseffected between the collar and the hub.

On the stock of the axleb' is secured an ap proximately U-shaped bearing10, on which is pivotally mounted the shank 11 of ashield 12. A spring14 is attached to the axle and bears against this shank 11, so as tohold the shield in the position indicated by dotted lines in Fig. 2 orin that indicated by full lines in said view. In the operative positionof the shield 12 (see full lines in Fig. 1) the shield lies over theflanged inner portion of the collar 8, almost in contact with the outersides of the collar, the spring 14: serving to uniformly hold the shieldsupported in this position and preventing it from bearing against thecollar. The shield 12 is approxi mate] y semicircular in form, so as tolie over the top half of the collar and so as to shed the sand downaround the sides of the same, pre venting the sand from passing inwardbetween the shield and the flange S of the collar. As will beunderstood, the shield 12 may be readily thrown up to the operativeposition (shown in dotted lines in 1) when it is desired to remove thevehicle-wheel from the journal or to effect any other operation withwhich the shield would otherwise interfere.

Having thus described my invention, I claim as new and desire to secureby Letters Patent'- 1. The combination of an annulus adapted to besecured to the inner end of a vehiclehub and to encircle the axle,ashield curved to lie over the upper portion of the annulus and providedwith a shank extending inwardly from the annulus longitudinally of theaxle, a bearing in which the shank is pivotally mounted, and a springattached to the axle and engaged with the shank of the shield to sustainthe shield yieldingly in position.

2. The combination of a sand-shield having a shank, a bearing in whichthe shank is pivotally mounted to move on the pivot toward and from thewheel=hub-, and a spring extending longitudinally of the shank andbearing against the same to yieldingly sustain the shield in operativeposition.

3. The combination of an annulus adapted to be attached to the innerendof a vehiclehub, a pivotally-mountedsand-shield lying over the annulusand movable on the pivot toward and from the annulus, and a springbearing between the shield and the axle and actuating the sand-shield tosustain it yieldingly in position out of contact with the an- 5 nulus. vv

4:. The combination of a pivotally-mounted sand-shield arranged to moveon its pivot toward and from the wheel-hub, and a spring bearing betweenthe axle and the shield to yieldingly sustain the shield in operativepo- 10 sition.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

EDWIN H.'WILSON.
